Chilcot on WMDs 'accounting problem'

Sir John Chilcot tells MPs it would be "quite extraordinary" if weapons of mass destruction were found in Iraq, 13 years on from the invasion.

Giving evidence to MPs on his inquiry into the war, Sir John said any discrepancies on the number of WMDs documented were "an accounting problem, quite simply", rather than a "hidden arsenal".

He was responding to a question from Conservative MP Julian Lewis, who chairs the Commons Defence Select Committee.
